"When you drink non-homogenized milk, your system absorbs native milk-fat globule membrane (MFGM) proteins. These are normally digested in the stomach or gut. However, homogenization decreases the size of milk-fat globules, making caseins the main protein fraction that the body absorbs. Homogenization allows for a greater amount of casein micelles to bypass normal digestion processes and be absorbed directly into the bloodstream."

What are the health effects of this? The research is not quite developed yet, but some suggest that the absorption of xanthine oxidase, an enzyme attached to milk’s fat globules, can cause hardening of the arteries, leading to angina, heart attacks, congestive heart failure, and strokes.
